Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional ECG measurement devices are used, then ECG signal measurement accuracy is ensured, but device portability and ease of carrying deteriorate

Engineering Contradiction:
ImproveportabilityVSAvoidECG signal measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The ECG measurement device is divided into multiple independent parts (first part with first electrode, second part with second electrode) connected by a flexible printed circuit board. This segmentation allows the device to be folded into a compact form for easy carrying, while maintaining the functional integrity needed for accurate ECG signal measurement when deployed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible printed circuit board enables the device to dynamically change its configuration between a folded compact state for portability and an unfolded functional state for measurement. This dynamic transformation resolves the contradiction between compact size and measurement capability.

Inventive Principle:
Principle #15Dynamics

2Loss of time

If ECG signals are measured immediately with portable devices, then response time is improved, but measurement reliability may deteriorate due to signal quality issues

Engineering Contradiction:
Improveresponse timeVSAvoidmeasurement reliability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The device performs preliminary actions by forming a closed loop configuration before measurement to ensure proper electrode contact and signal quality. The flexible printed circuit board is pre-configured to guide proper placement, ensuring that when measurement begins immediately, the signal quality is already optimized for reliable results.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The processing circuit receives feedback from the electrode configuration status to determine when a closed loop is properly formed. This feedback mechanism ensures that measurement only proceeds when proper contact is established, maintaining reliability while enabling immediate measurement once the device is deployed.

Inventive Principle:
Principle #23Feedback
